Description

Technical Field

[0001] This utility model relates to the field of lubricating oil reaction vessel technology, and in particular to a sealing device for a lubricating oil reaction vessel. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. As long as it is applied between two relatively moving objects and can reduce the friction and wear caused by the contact between the two objects, it is called lubricating oil. With the increase in the use of lubricating oil, the use of lubricating oil reaction vessels is also increasing.

[0003] Currently, in the use of related technologies, lubricating oil reactors generate certain harmful gases inside. Most reactors, such as the sealing mechanism for a lubricating oil reactor (publication number CN207569212U), are sealed and cannot release and purify the harmful gases generated inside during the reaction. As a result, when discharging the material after the reaction, the harmful gases are released into the outside, which may not only harm the workers but also the environment. Therefore, we propose a sealing device for a lubricating oil reactor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sealing device for a lubricating oil reactor, which has a unidirectional flow mechanism and a sealing mechanism to prevent outside air from entering the reactor and reducing the quality of lubricating oil production. It is also equipped with a filtration and purification mechanism to filter and purify harmful gases, so as not to cause environmental pollution and ensure the health of personnel.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sealing device for a lubricating oil reaction vessel, comprising a vessel body used for lubricating oil production, a feed pipe fixedly connected to the top of the vessel body, a sealing cap threaded onto the outer side of the feed pipe, an outlet pipe fixedly connected to one side of the vessel body, a left cylinder fixedly connected to one end of the outlet pipe, a right cylinder threaded onto one end of the left cylinder, a filtration and purification mechanism provided between the left and right cylinders, a one-way flow mechanism provided on the outlet pipe, a sealing mechanism provided on the right cylinder, a common connecting rod movably connected between the outlet pipe, the left cylinder, and the right cylinder, and a discharge pipe fixedly connected to the bottom of the vessel body, with a control valve provided on the discharge pipe.

[0006] A further feature of this invention is that the unidirectional flow mechanism includes a left partition and a right partition fixedly sleeved inside the air outlet pipe. A left through hole is provided on one side of the left partition, and four right through holes are provided on one side of the right partition. A spring is fixedly connected to one side of the right partition, and a sealing head is fixedly connected to one end of the spring. The sealing head is slidably and sealingly sleeved inside the left through hole.

[0007] By adopting the above technical solution, the sealing head can be squeezed into the left through hole by the setting of spring one and spring two, thereby sealing the gas outlet pipe and preventing outside air from entering the vessel. At the same time, when the pressure of harmful gas generated in the vessel is high, it will overcome the elastic force of spring one and spring two, causing the sealing head to move to the right, thus preventing the sealing head from sealing the left through hole. At the same time, the sealing head drives the connecting rod to move to the right, which can push the cover plate open to the right, allowing harmful gas to enter the left and right cylinders through the right through hole.

[0008] A further feature of this invention is that the sealing mechanism includes four left ear plates and four right ear plates fixedly connected to the outside of the right cylinder. The same cover plate is fixedly connected to one side of the four right ear plates that are close to each other. A sealing gasket is fixedly connected to one side of the cover plate. The same spring is fixedly connected between the left ear plates and the right ear plates. The sealing head is fixedly connected to one end of the connecting rod, and the other end of the connecting rod movably abuts against one side of the sealing gasket.

[0009] By adopting the above technical solution, under the elastic force of spring two, the cover plate and the sealing gasket can be firmly abutted against the outside of the right cylinder to seal the right cylinder, prevent outside air from entering and causing pollution to the coarse and fine filter screens and activated carbon screen, and at the same time prevent outside moisture from being absorbed and saturated by the activated carbon screen, thus reducing the effect of harmful gas absorption.

[0010] A further feature of this invention is that a telescopic rod is fixedly connected between the left ear plate and the right ear plate, a spring is sleeved on the outside of the telescopic rod, a spring is sleeved on the outside of the connecting rod, and the connecting rod is slidably sleeved inside the right partition plate.

[0011] By adopting the above technical solution, the cover plate, right ear plate, spring 1 and connecting rod can be wired to make their movement more stable and smooth.

[0012] A further feature of this invention is that the filtration and purification mechanism includes two retaining rings, which are respectively fixedly connected to the inner walls of the left and right cylinders. From left to right, a coarse filter, an activated carbon mesh, and a fine filter are movably abutted between the two retaining rings. The coarse filter, activated carbon mesh, and fine filter abut against each other. A guide ring is fixedly sleeved inside each of the coarse filter, activated carbon mesh, and fine filter. The connecting rod is slidably sleeved inside the three guide rings.

[0013] By adopting the above technical solution, harmful gases can enter the left and right cylinders through the right through hole. After being filtered and absorbed by coarse and fine filter screens and activated carbon screen, the harmful gases can be purified. The purified gas is discharged from the right end outlet of the right cylinder.

[0014] A further feature of this invention is that a threaded pipe is fixedly connected to one side of the left cylinder, and the threaded pipe is threadedly sleeved on the outside of the air outlet pipe.

[0015] By adopting the above technical solution, the left cylinder can be installed and disassembled.

[0016] A further feature of this invention is that a drive motor is fixedly connected to the top of the vessel body, and a stirring paddle is fixedly connected to the output shaft of the drive motor.

[0017] By adopting the above technical solution, it is easier to stir and mix the lubricating oil, thus improving its reaction effect.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model, through the setting of spring one and spring two, can squeeze the sealing head into the left through hole, thereby sealing the gas outlet pipe and preventing outside air from entering the vessel body. At the same time, when the pressure of harmful gas generated in the vessel body is high, it will overcome the elastic force of spring one and spring two, causing the sealing head to move to the right, thus preventing the sealing head from sealing the left through hole. Simultaneously, the sealing head drives the connecting rod to move to the right, which can push the cover plate open to the right, allowing harmful gas to enter the left and right cylinder bodies through the right through hole.

[0020] 2. In this invention, harmful gases can enter the left and right cylinders through the right through-hole. After being filtered and absorbed by coarse and fine filter screens and activated carbon screen, the harmful gases can be purified. The purified gas is discharged from the right end outlet of the right cylinder.

[0021] 3. Under normal circumstances, the cover plate and sealing gasket can be firmly pressed against the outside of the right cylinder by the elastic force of the second spring to seal the right cylinder, prevent outside air from entering and contaminating the coarse and fine filter screens and activated carbon screen, and at the same time prevent the activated carbon screen from being saturated by the absorption of external moisture, thereby reducing the absorption effect of harmful gases.

The same spring 75 is fixedly connected between the left ear plates 77 and the right ear plates 74. The sealing head 94 is fixedly connected to one end of the connecting rod 73. The other end of the connecting rod 73 is movably abutted against one side of the sealing gasket 72.

From left to right, the two retaining rings 81 are in sequential motion abutting against a coarse filter screen 83, an activated carbon screen 84, and a fine filter screen 85.

[0035] Specifically, the coarse filter screen 83, the activated carbon screen 84, and the fine filter screen 85 abut against each other, and each of the coarse filter screen 83, the activated carbon screen 84, and the fine filter screen 85 is fixedly fitted with a guide ring 82, and the connecting rod 73 is slidably fitted in the three guide rings 82.
